Usually, phase matching is a condition for achieving a high efficiency in such processes.
This occurs only in a limited bandwidth.
However, by manipulation of the parameters which influence the phase matching, it is possible to shift the wavelength range where the nonlinear interaction is strong.

Parametric processes are usually polarization-dependent: the nonlinearity itself is polarization-dependent, and at least in cases with a χ(2) nonlinearity also the phase matching, because such media exhibit birefringence.

Stand up for Science!

It is acceptable that some don't know much about photons, biological evolution or global warming.

But we don't want bigot ignorants to make political decisions and educate our children!

For example, global warming is not a matter of political opinion, but a fact. Ruthless profiteers are leading astray uneducated people, seducing them to take utterly irresponsible positions. But we cannot risk catastrophic climate changes! Science tells us it is high time to act. Read, for example, the IPCC Synthesis Report 2014.
